What should be verified about the tractor's gauges and warning lights as part of the in-cab brake check?
- A.Warning lights can be covered if they are distracting
- B.Only the speedometer is part of a brake check
- C.A failed low air buzzer is acceptable if the lamp works sometimes
- D.Gauges should read sensibly and warning devices should work, so the driver can detect a pressure loss immediately
Correct answer
D. Gauges should read sensibly and warning devices should work, so the driver can detect a pressure loss immediately
Why
The driver manages an air brake failure through gauges and warnings, so those instruments are part of the safety system. A warning that does not work removes the early notice the system is designed to give.
